Prospects of CKM elements $$|V_{cs}|$$ | V cs | and decay constant $$f_{D_{s}^+}$$ f D s + in $$D_s^+\rightarrow \mu ^+\nu _\mu $$ D s + → μ + ν μ decay at STCF

Abstract We report a feasibility study of pure leptonic decay $$D_s^+\rightarrow \mu ^+\nu _\mu $$ D s + → μ + ν μ by using a fast simulation software package at STCF. With an expected luminosity of $$1~\mathrm {ab}^{-1}$$ 1 ab - 1 collected at STCF at a center-of-mass energy of 4.009 GeV, the stati...
